Use of restoration plantings to enhance bird seed dispersal at the roadside: failures and prospects

open access: yesJournal of Environmental Engineering and Landscape Management, 2015
Plantings are commonly used in roadside reclamation for ornamental purposes and for increasing slope stability and road safety. However, the role of these plantings in restoring ecological processes, such as seed dispersal, has received little attention.

Effectiveness of the obligation of keeping forest strips for native forest connectivity and conservation in the dry Chaco, Argentina

open access: yesForest Systems, 2022
Aim of study: The Chaco Region is one of the main deforestation hotspots in Latin America. Forest strips, i.e. native forest strips that surround cultivated areas, were established by the end of 1980’s as an attempt to mitigate the effects of wind ...

Experimental exploration over a quantum control landscape through nuclear magnetic resonance

open access: yes, 2014
The growing successes in performing quantum control experiments motivated the development of control landscape analysis as a basis to explain these findings.When a quantum system is controlled by an electromagnetic field, the observable as a functional ...

A semantic and language-based representation of an environmental scene [PDF]

open access: yes, 2010
The modeling of a landscape environment is a cognitive activity that requires appropriate spatial representations. The research presented in this paper introduces a structural and semantic categorization of a landscape view based on panoramic photographs

Direct and cascading effects of landscape structure on tropical forest and non-forest frugivorous birds.

open access: yesEcological Applications, 2018
Global biodiversity is increasingly threatened by land-use change, but the direct and indirect drivers of species diversity in human-modified tropical landscapes are poorly known.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The third dimension in landscape metrics analysis applied to Central Alentejo-Portugal [PDF]

open access: yes, 2010
Landscape metrics have been widely developed over the last two decades, although the question remains: How does landscape metrics relates with ecological processes?

Protein Structure Prediction: The Next Generation

open access: yes, 2006
Over the last 10-15 years a general understanding of the chemical reaction of protein folding has emerged from statistical mechanics. The lessons learned from protein folding kinetics based on energy landscape ideas have benefited protein structure ...

Accelerating universe emergent from the landscape [PDF]

open access: yes, 2007
We propose that the existence of the string landscape suggests the universe can be in a quantum glass state, where an extremely large viscosity is generated, and long distance dynamics slows down.

Impacts of park landscape structure on thermal environment using QuickBird and Landsat images

open access: yesChinese Geographical Science, 2017
Urban parks composed mostly of vegetation and water bodies can effectively mitigate the urban heat island effect. Many studies have investigated the cooling effects of urban parks; however, little attention has been given to park landscape structure ...
